Never Lose Your 2FA Codes Again.
Device loss shouldn't mean lockout. Zunoy Cloud adds encrypted backup & seamless sync across all your devices.
What Is Cloud Sync?
Cloud Sync securely backs up your 2FA codes to the cloud, then keeps them synchronized across all your devices. It’s your safety net against losing access to your accounts.

Launch the app and navigate to your account settings.

Frequently Asked Questions
What is Cloud Sync?
Cloud Sync securely backs up your 2FA codes to the cloud and keeps them synchronized across all your devices, so you're never locked out if you lose your phone.
How do I enable Cloud Sync?
Open the Zunoy app, go to Settings, choose Enable Cloud Sync, and set your Personal Encryption Key. Your codes are encrypted on your device before they ever leave it.
What is the Personal Encryption Key, and can Zunoy recover it if I forget it?
Your Personal Encryption Key is the master password that protects your cloud backup. You create it, and only you can decrypt your synced codes — not even Zunoy can read or reset it, so if you forget it, your backup cannot be recovered.

Is my data encrypted?
